IMPRQVEMENT IN DOOR-SILLS.

www.

'o all whom it man coneern; v. Be it known that we, JOSEPH JOHNSTON and En- MUND O. MARLOW, of Brodheafl, in the county of Green and in the State of Wisconsin, have invented l l edge, with a strip which tits into salti groove, holding certain new and useful Improvements in Doorjills; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of ret'cri ence marked thereon making a part of this specification.

The nature Of Our invention consists iu the con struction of a door-sill with rubber weatl|er-strip attached.

In order to enable Others skilled in the art to which our invention appertains to make and use the same, we will now proceed to describe its construction and operation,rterringto the annexed drawing, in which- Figure l is a perspective view, and

Figure 2 is an end view of our door-sill.

A represents a doorsill or threshold, oi' any suitable construction, provided on' its upper side with a longitudinal groove for the insertion ot' a sliding bar, B.

In slots or grooves, on the upper side of the sliding bnr, is inserted a rubber strip, C, curved upward, as shown in the drawing.

This slidefivith rubber inserted, can be applied to any threshold by making a groove for it, and, when it is worn, it does not require that threshold and all be laid aside for a new one, but merely a new sliding bar, which, ofcourse, costs considerably less.

We are aware that a door having a groove on its` a bulgerl piece ot" rubber between the strip and groove, is not new. Our invention is applied to a door-sill with a groove in it. lhe bulged rubber is inserted in obliquo grooves in the movable strip, which fits into the. groove in the door-sill, and not bctwccn thc strip and the groove, as above cited, which acts :is a wedge for the rubber.

What we claim is* The combination of the grOOvcd sill A and movable strip B, provided with oblique grooves, into which is inserted the bulged rubber (l, all as shown and doscribed.

In testimony that we claim the foregoing, we have hereunto set our hands, this 17th day oi March, 1570.
